摘要:
A railroad rail support includes a first and second horizontally oriented rubber tire having a circumferential tread, a top sidewall including a top rim bead and a bottom sidewall having a bottom rim bead, said-bottom sidewall and bottom rim bead being adjacent to a railroad roadbed. First and second rail support members within each tire have a top surface in the plane of the top rim bead and a bottom surface in the plane of the bottom rim bead, and include a top plate and a plurality of tubular channels extending downwards from said top plate to the bottom surface. A concrete matrix fills each rubber tire and retains the rail support within the rubber tire. Railroad spikes are installed into the tubular channels have heads overlapping the opposed edges of the bottom flange of a first and a second railroad rail. Each spike is locked into its respective tubular channel by extending downwards in a generally vertical direction with a second contiguous portion at an angle of at least 30.degree. from the vertical direction to said first portion. A female threaded member retained within each rail support member is on a common horizontal axis at a right angle to the rails, the female threaded members extending through each respective tire tread. A rail spacing adjustment has a first end extending into the first rail support female threaded member and has a right-hand thread and having a second end extending into the second rail support female threaded member and having a left-hand thread.
摘要:
Fastening strap composed of a rod having a vertical rectilinear part (20) and a curved part which forms a spring and the end (10) of which grips the flange (25) of the rail to be fastened, after being tensioned as a result of the rotation of the strap above a ramp (30), the lower end of the rectilinear part being equipped with a heel (2) catching on a retaining surface (36) in the tie. The strap has an intermediate bearing point (6) which, during the rotation of the strap, bears on an abutment (38) or on a bearing surface of a metal sole plate. This intermediate bearing point ensures the stability of the strap during its rotation and in its tensioned position and, if an abutment is used, keeps this abutment in place.
